The segment that begins, “I woke last night to the sound of thunder, ‘How far off?’ I sat and wondered,” is as universal as anything in Seger’s catalog. It’s his perspective, however, that shifts the song from teenage action to adult meditation and gives goosebumps to everyone within earshot.

That onstage sensation likely will be hard to give up if Seger decides to retire after the current “Runaway Train” tour.

The 72-year-old Detroit icon has made no official announcement regarding retirement, but the video unveiling the tour included the wording "on the road again, up on the stage, one last time."

Klipsch Music Center served as the tour’s fourth date, a night that will provide lasting thrills for fans.

By math, Saturday’s audience was Seger’s biggest ever in Indianapolis — with Klipsch at 24,000 edging the capacity of Bankers Life Fieldhouse (20,000) and bygone Market Square Arena (18,000).

Seger appeared to be in robust health, aside from a brief gag in his throat when introducing members of the Silver Bullet Band (unrelated to the task at hand).

Wearing an Indian Motorcycle T-shirt, blue jeans and eventually a Detroit Tigers baseball cap, Seger looked as if he could ride into the sunset or just as easily come back for another show next summer.

If the singer-songwriter does hang it up, Silver Bullet guitarist Rob McNelley will be the hottest free agent since Kevin Durant.

McNelley, a past Academy of Country Music “guitar player of the year” honoree, nailed the muscular licks of “Her Strut,” brought slide-guitar life to “Like A Rock” and roughed up the conclusion of “Old Time Rock & Roll.”

Amid a segment of three songs recorded after the 1980s, Seger performed “It’s Your World” — a 2014 tune based on climate change: "All these children have to face our mess someday," he sang.

He prefaced the song by urging prayers “for everybody in Texas" confronting the effects of Hurricane Harvey.

Earlier, Seger commented on the Labor Day weekend weather in Indiana: “I don't think we could have a better night.”

By evening’s end, the statement applied to all aspects of the show.
